Siderite

Siderite is a mineral composed of iron carbonate FeCO 3.It takes its name from the Greek word sideros, "iron". It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus.Both magnesium and manganese commonly substitute for the iron.. Its crystals belong to the hexagonal system, and are rhombohedral in shape, typically with curved and …

Magnesium and manganese may substitute for the iron. Siderite crystals are yellow to dark brown in color, rhombohedral in shape, and with curved and striated faces, and also occur in masses. Siderite is commonly found in bedded sedimentary iron ores, including banded iron formations (BIFs, see entry Banded Iron Formations), and in hydrothermal ...

Siderite Value, Price, and Jewelry Information

What is Siderite? Siderite forms three solid-state solution series. It's the iron (Fe) analogue in a series with manganese (Mn) dominant rhodochrosite. It also forms the Fe-end of a series with zinc (Zn) dominant smithsonite, as well as with magnesium (Mg) dominant magnesite. Siderite has been used as an iron ore and for steel production.
